Reflexw - GPR and seismic processing software

With more than 1400 sold licences our software Reflexw is one of the world's most popular geophysical near surface processing and interpretation packages.

It covers the complete range of wave data (seismic, GPR, ultrasound) and the different geometry assemblings (surface reflection and refraction, borehole crosshole and tomography and combination of borehole and surface measurements). You may also have a look at a one side broschure for GPR, reflections seismics, refraction seismics and borehole application.

This crosstable gives you a summary of the useful combinations of the available modules and the individual applications.

Overview of the different modules:

2D-data analysis:

Easy import of data of many different formats (e.g. SEGY, SEG2, most of the GPR- and seismic systems (GSSI, RAMAC, PULSE-EKKO, ABEM, OYO, Summit, IDS, UTSI and so on)), integration of other non-standard formats.

Full GPS support

Many different processing possibilities - interactive processing of single files or by generating a batch-file, one- and multi-channel filters, editing, static correction, deconvolution, migration and much more. All processing steps are documented.

Interactive adaptation of diffractions or first arrivals giving an estimate of the average velocities

Picking of arrivals - manual, automatic or semi-automatic, ASCII-conversion of the picks

Interactive velocity analysis of CMP- or shot-data using a semblance analysis or an interactive adaptation method calculating either the reflection hyperbolas (reflection seismics) or the complete traveltime branch including diving waves (refraction seismics).

3D-datainterpretation:

easy generation of a 3D-dataset from individual 2D-lines which may be parallel, crossing or randomly spaced wihtin the xy-plane

Display of x-,y- or z-slices. The slices are either displayed in manually scalable windows or by moving through the 3D-dataset using a track bar

3D-cube display of the individual slices or of the full 3D-data using shading algorithms

3D-Picking of arrivals

modelling (simulation/inversion)

refraction traveltime analysis for refraction seismics

various sorting and combining possibilities for the picked traveltimes

these combined traveltimes are the bases for a FD based wavefront inversion

different raytracing methods are available for the evaulation of synthetic traveltimes

forward modelling for simulating the electromagnetic and seismic wave propagation in a 2-dimensional medium using a Finite Difference scheme

A 2D-tomographic approach based on SIRT is incorporated for the inversion of the picked traveltimes (refraction and transmission). Straight and curved rays are supported. A 3D-tomography is available for transmission traveltime data.
